    Betty Boost dindt work :(

    PCB needs both R23 & C10 for MID Pot.

    Hydra Delay Mod

    I made a toggle switch(DPDT on-off-on) for select C11. It's 2n2-off-3n9. Off mode gives very natural wet sound and it makes me feel like stand on cloud. Off & Age knob 12o'clock is my choice. 3n9 is also good - not big difference but feel so good. 2n2 doesn't need any more. I strongly recommend...

    Photon Vibe more speed

    Let me talk about charge pump IC. If you use LT1054 or 7660 type, maximum speed is so slow. I dunno why. It must be 1044 type IC. I prefer TC1044scpa. If you want more speed change R14&R15 -> 3k9.

    Photonvibe speed up?

    3k9. 2k2 have a problem. Speed knob not works properly at 2k2. https://forum.pedalpcb.com/threads/photonvibe.1255/

    Semi-Sweet Distortion Mod

    Sustain Potentiometer - C50K. It's correct curve for Sustain.

    Paragon (KoT)

    C10, C11 -> 100uF C21, C22 -> empty D7 -> 5817 D14, D15 -> bypass, using jumper and connect below hole of both d14 & d15.

    Covert Overdrive too wooly

    I always using DLSmk3 with other drive pedal(like Tubescreamer, treblebooster, MXR dist+). Those pedal cuts the low frequency and make high frequency brighter. Do not mod DLSmk3 pedal.

    Paragon (KoT)

    The idea was from freestompbox site. http://freestompboxes.org/viewtopic.php?f=7&t=382&hilit=king+of+tone&start=400

    Paragon (KoT)

    There are four toggle switches on case (instead of DIP s/w on PCB). Using carbon film resistors and carbon composition resistors like an original KoT. MSPA18 transistor's emitter-base was used for MA856 diode and it sounds really good ! I don't need 18V so charge pump IC isn't on PCB.

    Hydra Schematic

    Just 1k. I didn't change value.

    Hydra Schematic

    Age pot not helped for me. I only change R17 to carbon film resistor a few minutes before. The result is very very positve.

    Hydra Schematic

    I hope to see it. Wet sound is too bright for me so, I want to change to carbon film resistors for FV-1 output. However,, we have not schematic yet.

    Hydra Delay Mod

    1. MIX Potentiometer B10k -> A10K 2. If you don't like too much bright wet sound, using carbon film resistors for both R17 & R18. 3. C11 -> 3n9.

    Hydra Delay Dry/Wet mix

    3 o'clock? Mine is 11 o'clock for 50:50 mix. I'll change B10K to A10k for Mix. Maybe it's much better than now.

    Corduroy Fuzz (velvet fuzz)

    Both modes are useful but I prefer Big Muff mode.

    Hydra Delay Dry/Wet mix

    When Mix knob is noon, wet signal is slightly louder than dry signal, IMO. This difference makes fine adjustment difficult. Any solutions?

    Corduroy Fuzz (velvet fuzz)

    I checked this and it wasn't no sound but very low volume. Thank you.
